6. Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

a

The potential energy decreases because the train moves in the same direction as the

magnetic force.

b

The potential energy decreases because the train moves against the magnetic force.

С

The potential energy increases because the train moves against the magnetic force.

d

The potential energy does not change because the magnets in the system do not change.

Yeah

Potential energy increases because the train moves against the magnetic force.

Explanation:

When the magnetic toy train is moved away from a magnet that cannot move, the potential energy in the system of magnets during the movement is affected as there's an increase in the potential energy because the train moves against the magnetic force.

We should note that the potential energy simply means the energy that is stored in the magnetic toy. Since the magnetic toy has been moved away from the magnet, the likelihood of its attraction will reduce thereby there'll be a rise in the potential energy.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
